Install the Module

After installation, you will see the new "Multi Invoice Payment" tab in all payment forms with enhanced allocation capabilities.

Creating Payments with Multi-Allocation

Navigate to Accounting → Payments and create a new payment.
Select the partner - the system automatically shows their open invoices in the allocation tab.

Understanding the Allocation Interface

The allocation tab shows:
- Invoice/Bill: Select from open documents
- Paid Amount: Already paid amount for each invoice
- Due Amount: Remaining amount due
- Mark Fully Paid: Checkbox to allocate full due amount
- Amount: Field to enter specific allocation amount

Auto-Allocation Feature

Enable "Auto Allocation" to automatically distribute the payment amount:

How it works: System allocates amounts starting from the first invoice until payment amount is exhausted
Benefit: Saves time when you want to pay multiple invoices with available payment amount

Manual Allocation Control

For precise control, disable auto-allocation and:
- Enter specific amounts for each invoice manually
- Use "Mark Fully Paid" to quickly allocate full due amount
- Monitor "Assigned Payment Amount" and "Difference Payment Amount"

Validation: System prevents over-allocation and shows errors for invalid amounts

Multi-Currency Handling

The module automatically handles currency conversions when:
- Payment currency differs from invoice currency
- Company currency differs from transaction currencies
All allocations are properly converted using current exchange rates.

Payment Validation & Reconciliation

When you post the payment:
- System creates proper accounting entries for each allocation
- Automatic reconciliation with respective invoices
- Zero-amount allocations are automatically removed
- Complete audit trail maintained
